anyone know the benifits of lightweight wheels?

It is a best-fit rule of thumb that some people use to simplify the performance advantage of lighter cars.

I've heard "old timers" make a similar claim...only the ratio was 1:7 ...

There is a range of claims but 1:4 sounds a little less optimistic than a 1:7 ratio. My scanning of other internet forums suggests 1:4 is more commonly accepted.

Then maybe my calculation of less than 1% is correct? If the stock wheel weight is 15-16lb and you went with a 10-11lb, then you would save ~5lbs per wheel, or 20lbs total. 20x4=80lbs... imagine a race between two stock Yari...the only difference being, one the driver weights 120lbs, the other 200lbs ... sounds like a dead heat to me?
